FOLDING COT.

SPECIFICATION forming part of Letters Patent No. 718,159, dated January13, 1903.

Application filed April 22,1902. Serial No. 104,141. (No model.)

To all whom/'it may concern:

Be it known that I, CARL GUsrAE RUND- GVIST, a citizen ot the UnitedStates, residing at Atlantic City, county of Atlantic, and State of NewJersey, have invented a` certain new and useful Improvement in FoldingCots, of which the following is a specification.

My invention relates to a new and useful improvement in folding cots,and has for its object to provide a cot which may be folded into a verysmall space, so as to be compact for transportingfroin one place toanother, but when extended and set up will be as stable and efficient inaction as an ordinary solid cot.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand howto make and use the same, the coustructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specication, in which- YFigure A1 represents a side elevation of the cot set up; Fig. 2, alongitudinal section of the cot; Fig. 3, a section on the line 3 3 ofFig. l; Fig. 4, a sectionon the line4 40E Fig. 1; Fig. 5, a detail viewshowing the tool used for tightening the stretcher; Fig. 6, a detailview showing themanner in which the headrest is attached to the siderails of the cot; Fig. '7, a perspective view of one of the side rails,the stretcher, and one ofthe folding supports, all folded ready fortransportation.

In the drawings, A represents the side rails of the cot, which areformed in two parts, the parts being hinged together at the point B, andthese two parts are adapted to Abe heldin alinement with one anotherwhen extended by means of the hooks C upon each side of the side rails,which hooks are pivoted to one part of the side rails and adapted tohook over a pin in theother part. One end of each of the side rails hasformed through it square openings, in which are adapted to be insertedthe square trunnions D of a circular cross-piece D', to which isattached one end of a stretcher E, consisting of canvas or like flexiblematerial. The other end of the side rails A have formed through themcircular openings in which are adapted to it the hubs F of ratchetwheelsF'. These hubs F have an annular groove formed in the same, and threadedthrough the end of the side rails are screws F2, the ends of which areadapted to extend in the annular grooves, and thus hold theratchet-wheels in place upon the ends of the side railsto allow rotarymovement of said ratchetwheels. Through the hub F and ratchet-wheels F'are formed 'square openings in which are adapted to' fit 'square studs Gof the roller G', which extend between the side rails. To this roller issecured the other end of the stretcher E, and when it is desired totighten the stretcher a tool H, such as illus- I, pivoted Yto the siderails and engaging the ratchet-wheels, prevent any retrograde movementafter the stretcher has been tightened upon the outside ofthe siderails. Near each end are secured tapering sockets J, in which areadapted to be inserted the tapering uplofthese strips to each two legsof the cot,

and each set of two cross-strips cross one another and are pivotedtogether at the center at the point L'. The other end of each of thecross-strips L has secured thereto right-angle lipsL2, which are adaptedto'be inserted in eyes or clips' M, secured to the inner side of each ofthe side rails. Thus the folded support, composed of the legs K andcrossstrips L, will not only supportthe cot, but will keep the siderails from spreading by reason vof the lips L2 being inserted in theeyes or clips M, and when thecot is properly set up it will make a verysolid structure.

N Ais a head-rest which is secured to inclined blocks N upon each side,and the under side of these blocks are recessed at N2, and in the recessis provided a short rod N3, which is adapted to enteran eye O, securedto one end of each ofthe side rails .upon their upper surface. Thus byinserting therod N3 IOO into the eye upon each side the head-rest issecured to the cot, and it can be quickly and easily removed at anytime.

When it is desired to fold the cot, each of the folding supports isremoved from the side rails by removing the lips L2 from the eyes orclips M and removing the legs from the sockets J. Each of these supportscan then be folded, as shown in Fig. '7. Then the side rails are free tobe spread so that the circular cross-piece D can be removed, as also theroller G, and the stretcher can then be rolled upon one of the rollers,as shown in Fig. 7, and then by unhooking the hooks C of the side railssaid side rails can be folded, as shown in Fig. 7. When all the partsare thus folded, they may be packed in a comparatively small space, anda bag or covering could be provided for holding the different parts witha strap passing around the same for carrying, or all the parts could bepacked in an ordinary trunk.

Of course I do not Wish to be limited to the exact construction hereshown, as slight modifications could be made without departing from thespirit of my invention.

Having thus fully described my invention, what I claim as new and usefulis l. In a folding cot, side rails, each composed oftwopartshingedtogetherat the under side of the side rails, means for securing the twoparts of the side rails in line with one another, a removablecross-piece secured between the side rails at one end, a removableroller secured between the side rails at the other end, a stretcherattached at one end to the cross-piece and at the other end to theroller, a ratchet-wheel secured to the roller, a pawl pivoted to theside rails and adapted to engage the teeth of the ratchet-Wheel toprevent retrograde movement of the roller, tapering sockets secured uponthe outside of the side rails near each end, legs having tapering upperends adapted to itin the tapering sockets, cross-pieces, eachcross-piece pivoted at one end to the legs near their lower end, saidcross-pieces crossing and pivoted together in the center, right-anglelips secured to the other end of the cross-pieces, eyes or clips Securedto the inner end of each of the side rails into which the lips areadapted to t, substantially as and for the purpose specified.

2. In a folding cot, two side rails pivoted at the center and hingedtogether upon the under side, hooks pivoted to one member of each siderail and adapted to hook over pins secured to the other member, aVcylindrical cross-piece extending between the side rails at one end,square studs at each end of said cylindrical cross-piece adapted to tinsquare openings formed in the side rails, ratchet- Wheels arranged atthe opposite end of the cot, said ratchet-Wheels having hubs journaledwithin the ends of the side rails, annular grooves formed in the hubs,screws threaded through the side rails and entering the annular grooves,a roller, square studs protruding from each end of the roller andadapted to enter square openings provided through the ratchet-wheel,pawls pivoted to the side rails and adapted to engage the ratchet-wheel,a stretcher secured at one end to the cylindrical cross-piece and at theother end to the roller, tapering sockets secured to the side rails neareach end, legs having tapering upper ends adapted to fit in the sockets,cross-pieces pivoted at one end to the lower end of the legs andremovably secured to the side rails at the other end, said cross-piecesbeing pivoted together at the center, substantially as and for thepurpose specified.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing Witnesses.
